+For every run, the script also reads the latest filename-dated XLSX from each configured CellData directory. It builds CellData CGI as `460-00-{eNB/gNB}-{CI}` and adds coordinates to matching interference rows. Unmatched rows keep empty coordinates.

 The summary columns are:
 
 ```text
-hour_start,hour_end,cgi,cell_name,interference_dbm
+hour_start,hour_end,cgi,cell_name,interference_dbm,longitude,latitude
 ```
 
 The script never modifies or deletes source storage files. By default it writes the complete selected hour to MySQL and keeps only that hour in the target table.
 
-The database table contains one time column, `metric_time DATETIME`, which is the source KPI start time. A same-hour rerun replaces that whole batch. After a successful insert, rows for every other hour are deleted in the same transaction. The script refuses to replace a newer database hour with an older source hour.

 MySQL connection values, database `interference_etl`, and table `interference_hourly_summary` are constants at the top of `main.py`; they are not project environment variables. The script creates its database and table automatically when they do not exist.
 
+The five CellData directories are fixed in `CELL_DATA_DIRECTORIES`. In each directory, only XLSX files ending with a valid `YYYYMMDD.xlsx` date are considered, and the latest date is selected.
